NIST is conducting market research to identify sources capable of supplying a customizable FPGA-based GHz Multi-instrument meeting extensive minimum technical specifications for advanced dosimetry research. The required system must include at least 4 analog input and output channels, 5 GS/s ADC/DAC rates, 14-bit resolution, and software-configurable instrument functions such as waveform generation, oscilloscope, spectrum analysis, lock-in amplification, and PDH locking. NIST has not yet determined its acquisition strategy and encourages interested parties to voluntarily submit company details, product specifications, commercial pricing, and feedback on the draft requirements. No budget amount, performance location, or specific timeline has been provided in the notice. Interested suppliers should respond to help NIST assess potential competition for this requirement.
